Tamper-Resistant Torx Stainless Steel Rounded Head Drilling Screws
 |
Removable only with a tamper-resistant Torx driver, these screws drill and fasten in one step. The deep, six-lobe recess (also known as pin-in-Torx) prevents drivers from slipping and deters unauthorized access. These screws resist corrosion and have a rounded head to create a finished look.
Length is measured from under the head.
410 Stainless Steel—Tougher and more wear resistant than other stainless steel screws but less corrosion resistant.
Power Tools Bits—Pair with your power tools to turn screws more quickly than manual tools.

Tamper-Resistant Torx Steel Flat Head Drilling Screws
 |
Drill and fasten components with countersunk holes and deter tampering. These screws have a deep, six-lobe recess (also known as pin-in-Torx) that turns only with a tamper-resistant Torx driver. Their flat, beveled head sits flush with surfaces.
Length is measured from the top of the head.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
Power Tools Bits—Pair with your power tools to turn screws more quickly than manual tools.
